Hi ,

My name is***** am sorry to hear that you are having this issue.

I will be glad to assist you with this.

My goal is to give you the best experience possible!

When you see a circle with a slash symbol instead of the Apple logo, it means your Mac couldn't find a valid System Folder to start up from, try reinstalling macOS using macOS Recovery. You can start up from macOS Recovery and use its utilities to recover from certain software issues or take other actions on your Mac.

How to use macOS Recovery

Hold down Command-R on your keyboard immediately after pressing the power button to turn on your Mac, or immediately after your Mac begins to restart. Continue holding until you see the Apple logo or a spinning globe. Startup is complete when you see the utilities window:

After starting up from macOS Recovery, select Reinstall macOS (or Reinstall OS X) from utilities, then click Continue to Download and reinstall the Mac operating system.

What Customers are Saying:

Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill
